3M 7010512898 Spiral Band Aluminum Oxide 100 Grit

Product Description

The 3M 7010512898 is a coated abrasive spiral band designed for use with mandrel-mounted rotary tools and pneumatic die grinders. Built on a heavy-duty X-weight cloth backing, this band delivers consistent stock removal and surface finishing on metal, wood, and composites. At 100 grit with an aluminum oxide abrasive, it performs reliably in fine-grade deburring, blending, and contour sanding applications. The spiral construction allows the band to conform to curved and irregular surfaces, making it a practical choice for tight-radius work where flat abrasives cannot reach. Measuring 0.25 inches in diameter and 0.5 inches wide, it fits standard small-diameter mandrels used across metalworking and fabrication shops.

This spiral band is suited for metal fabrication, welding cleanup, and precision finishing tasks in industrial and trade settings. Common applications include deburring drilled holes, blending weld seams, and smoothing interior contours on machined parts. The fine 100 grit designation makes it appropriate for finishing passes rather than aggressive material removal. It is used by machinists, pipefitters, sheet metal workers, and maintenance technicians who require controlled surface preparation in confined areas.

Key Features

• Aluminum oxide abrasive for reliable cutting on ferrous and non-ferrous metals
• 100 grit fine grade suited for finishing, blending, and light deburring
• X-weight cloth backing provides durability and flexibility under rotary load
• Spiral band construction conforms to curved and contoured surfaces
• 0.25 inch diameter fits standard small-mandrel rotary and die grinder setups

Compatibility

Designed for use on mandrel-mounted rotary tools and die grinders that accept 0.25 inch diameter spiral bands. Consult mandrel manufacturer specifications to confirm fitment before installation.

Installation Notes

Installation is performed by trade professionals using standard die grinder mandrels rated for the band diameter. Ensure the tool is fully powered down and disconnected from the air supply before mounting or removing the band. Follow the mandrel manufacturer's seating instructions to prevent band slippage during operation. Eye protection and appropriate PPE are required when operating rotary abrasives.
